Here are all the price differences after checking that deal with 3 different hotel prices...
Value Resorts (Pop)
Flights, hotel, tickets (no dining plan), $150 spending money
£1267pp
Moderate Resort (Coronado Springs)
Flights, hotel, tickets, QSDDP, $150 spending money
£1678pp
Deluxe Resort (Animal Kingdom Lodge)
Flights, hotel, tickets, Normal DDP, $150 spending money
£2517pp

I think the best option would be for the moderate resort, QSDDP, and 5 or 6 table service meals throughout the stay, does that sound about right?
